Hello All I have a brand spanking new 40TB Hardware Raid6 array to play around with. I am looking for recommendations for which filesystem to use. I am trying not to break this up into multiple file systems as we are going to use it for backups. Other factors is performance and reliability. CentOS 5.6 array is /dev/sdb So here is what I have tried so far reiserfs is limited to 16TB ext4

Ok, downloading the BackupPC RPM directly did not work to myriad dependencies and sub-dependencies. How do I add the Test repository to my yum config, please?

I have CentOS 6.x installed on a "HP ProLiant DL380 G5" server. It has eight 750GB drives in a hardware RAID6 array. Its acting as a host for a number of OpenVZ containers. Seems like every time I reboot this server which is not very often it sits for hours running a disk check or something on boot. The server is located 200+ miles away so its not very convenient to look at. Is

Situation: two similar servers, both with CentOS 5.4 64-bit. Making an ext3 filesystem on one takes seconds, on the other minutes.

I have two openvz servers running Centos 6.x both with 32GB of RAM. One is an Intel Xeon E3-1230 quad core with two 4TB 7200 SATA drives in software RAID1. The other is an old HP DL380 dual quad core with 8 750GB 2.5" SATA drives in hardware RAID6. I want to figure out which one has better random I/O performance to host a busy container. The DL380 currently has one failed drive in the

Hi, I just received a new server (HP DL180G5) with 12x 1TB HDs and I bumped into fdisks 2TB limits... Since this is an entry level server, I can't use the classic HP bootable utilities to create smaller volumes et can only create a big RAID6. I found out that: using parted, labelling it gpt and creating the partitions would do the trick. But, what about grub? I read that it does not support

Hello, Let's say your operating policy is "no patch updates without testing first in the test environment". Let's say it takes you 3 weeks to test. Over the course of the 3 weeks, the repo changes (new packages added, old removed). Is there a way to "freeze" a set of packages so that when I run "yum update" on a Prod server it'll get the same package

Hi. Has the issue with rsync using a lot of memory if there are a lot of files been addressed in 3.0? I checked the rsync FAQ and it says this issue would require a major rewrite of rsync, not sure if that entry is up to date or not - 3.0 is a major rewrite AFAIK. Thanks, Aleksey

How much maximum memory will CentOS 5 support, please? The product info page at http://www.centos.org/product.html says 16GB, but I am running 80 GB RAM right now and seeing 80 GB in top. I see the same 16 GB limit on the RHEL page: http://www.redhat.com/rhel/compare/#note_4 The server hardware is capable of 192 GB RAM and I want to add memory, but want to be sure the OS will support it. Is

Hi. This page saved me a lot of trouble today, when my Xen 3 multi-bridge setup stopped working after updated from CentOS 5.5 to 5.7: http://www.centos.org/docs/5/html/Virtualization-en-US/ch-virt-bridge-errors.html However there were a couple of errors in the script: use of "op" instead of "OP" (variable name mismatch) and use of .. ,, instead of ;; in the shell

Hi. A friend of mine was doing real-time video decoding on Fedora Core 13 and he had a performance glitch (1/2 a second freeze) every 5-10 seconds. "top" showed flush-253:0 process at the moment of the freeze. Major device number 253 corresponds to device-mapper. I advised my friend to re-install his FC13 without LVM, to see if the glitch is related to LVM. After re-installing FC13

Hi. I've installed BackupPC 3.1.0 from Testing repository, to Cent OS 5.2 x86_64, and I am hitting an SE Linux denial - the httpd cannot talk to the BackupPC socket: type=AVC msg=audit(07/31/2008 17:18:53.623:410) : avc: denied { connectto } for pid=11767 comm=httpd path=/var/log/BackupPC/BackupPC.sock scontext=user_u:system_r:httpd_t:s0 tcontext=user_u:system_r:initrc_t:s0

Hi. Running CentOS 5 with the default GNOME desktop. Is it possible to configure xterm windows not to have title bars to get the most out of the available screenspace? I've tried to look this up but mostly find reference how to change the content of the title bar; I want to remove it completely. Found a reference to Compiz but the version available through CentOS seems old (0.0.13 compared

Hi. I am trying to recursively rsync a directory containing 13 million files. Right now this is killing my server, in terms of memory usage. I've upgraded from rsync 2.6.9 to 3.0.3 on both ends, but memory usage is still too high. I killed the rsync process when it reached 256 MB in size. I only have 1 GB of RAM in this server. We've planned an outage to upgrade it to 3 GB, but

If we''ve abandoned the idea of putting the number of redundant blocks into the top bits of the type bitmask (and I hope we have), then we''re fairly much there. Current code is at: git://, http://git.infradead.org/users/dwmw2/btrfs-raid56.git git://, http://git.infradead.org/users/dwmw2/btrfs-progs-raid56.git We have recovery working, as well as both full-stripe writes

Hi. I'm trying to get OTRS running on CentOS 5.5 with SELinux enabled, and audit.log / audit2allow tell me I need to add the local policy: #============= httpd_t ============== allow httpd_t unconfined_t:shm { unix_read unix_write }; which I think will allow the httpd access to read and write from shared memory? Is that right? What are the risks involved in opening this? I notice it is

How do I find out who is the maintainer of the php-pgsql package, please? I want to request upgrade from underlying postgresql-libs-8.1.21 (/usr/lib64/libpq.so.4) to postgresql84-libs-8.4.4 (/usr/lib64/libpq.so.5.2). Background on this request: Apache httpd's php's php-pgsql uses PostgreSQL 8.1 library (/usr/lib64/libpq.so.4), which leaks memory. PostgreSQL 8.4 library does not leak.

Hi. CentOS 5.4 64-bit with SELinux, happily running for over a year, suddenly httpd fails to start up, getting an error message like: Starting httpd: Syntax error on line X of /etc/httpd/conf.d/php.conf: Cannot load /etc/httpd/modules/libphp5.so into server: libxml2.so.2: failed to map segment from shared object: Permission denied I turned off SELinux and was able to start httpd.
